The active ingredient of Chorulon, human Chorionic Gonadotrophin (hCG), is a complex glycoprotein with luteinising hormone (LH) activity. In the female, hCG can be used to promote maturation of the follicle, ovulation and the formation of the corpus luteum. In the male, Chorulon stimulates the production of testosterone and thus influences the development and maintenance of primary and secondary male sexual characteristics.

Chorulon can be used in the following fertility problems in domestic animals:

-cases of repeated failure of conception in cows and heifers

-induction of ovulation in mares and bitches

-cases of cystic ovaries in cows and heifers

-anoestrus in mares and bitches

-delayed ovulation, prolonged pro-oestrus in bitches

-deficiency in libido in male dogs

Dosage and administration

See table. Reconstitute with the solvent provided, ensuring the freeze-dried plug is fully dissolved. Administer by intramuscular or intravenous injection, observing the usual aseptic precautions.
